MCU-CES

Management & Concentrator Unit with Circuit Emulation Service (CES)

for ULAF+ access platform

reliable

flexible

strong

The MCU-CES includes all the features of the MCU-S and the CES functionality. The MCU-CES is designed to run E1 voice and data services emulation over packet switched networks. Together with the ULAF+ transmission units the MCU-CES module optimizes performance and cost efficiency of metro Ethernet applications.
The ULAF+ CES centralized solution processes CES in the sub rack avoiding waste of bandwidth on the access links due to overhead of Ethernet packets. Furthermore the high integrated ULAF+ architecture minimizes the need for space in the central office and avoids additional cabling of data, power and management networks.
